Question

Briefly explain earth's daily rotation and annual orbit, defining the terms ecliptic plane and axis tilt.

Answer 1

The movement around the axis of the earth occurs once every 24 hours and it does so from a start point to finish in a term we can call complete revolution and it does this by day by day turn, every 24 hours. The yearly circle where the earth moves round the sun , however is a 365 transformation around the sun or ecliptic plane. It does this with the earth tilted at 23.5 degrees, off the opposite line to the ecliptic plane.
